Re: How do i work out an average?No. that doesn't make sense. An average should be representative of the values in the table and so somewhere between the lowest and highest values.

Re: How do i work out an average?Which of the places has more rainfall on average over the whole year? #130 20121210 06:29:07
Re: How do i work out an average?Ok. think about the information. You have 12 months data altogether; 8 then 4 months for A and 10 then 2 months for B. You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #131 20121210 06:46:32
Re: How do i work out an average?so would A be 13.3? #132 20121210 06:53:56
Re: How do i work out an average?Yes that's right. Notice the answer lies between 10 cm and 20 cm, but nearer to 10 because there were more months at that rainfall. You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #133 20121210 07:26:06
Re: How do i work out an average?Thank you so much! I'll try and remember that for the exam tomorrow! #134 20121210 08:34:57#135 20121210 08:40:03#136 20130114 04:24:41

Re: How do i work out an average?Hi Ella123; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
